Title: Contained direct particle beam flow abrasion system

Abstract: Systems for abrasive action include machinery for creating a vacuum and positive pressure to enable flow control while providing adequate vacuum to both retrieve and capture the spent abrasive material and the abraded material. A first embodiment includes a vacuum and boost operation facilitated by the use of a foot control for high control of abrasion, cleaning and polishing. A second embodiment is for use with human tissue and includes a vacuum only system with filtered air. A third embodiment includes vacuum with automatic boost for skilled medical personnel use and uses a minimum vacuum level to trigger a pre-set boost operation. The system utilizes air filtration, ultra violet, heat oven sterilization and secure waste storage. A manual contact tool is used closely with the area to be abraded supplanting any other control other than the pressing of the manual contact tool against the surface to be abraded, to create sufficient vacuum to trigger boost operation. A hand-held direct particle beam abrasion manual contact tool having a prophylactic tip which creates a concentric space within which the kinetics of focussed direct impact and radial collection of spent abrasive particles and abraded material is collectably withdrawn. A flow accelerator within an annular insert of the manual contact tool and prophylactic tip can be varied to suit many applications.
